Advantage...individual investor!

The advantage is I have full control over the process and can and do work with those customers with abnormal circumstances.

Totally agree with @Steven Wilson , get a property management company run your rental. and just another advantage, a property management company has the benefit of being viewed and treated as a professional entity.

$300 bucks spent in one hour.This $300 means WAY more to the resident who most likely does not have the advantages or opportunities that real estate have been able to provide you and your family.

An advantage of turnkey is that it allows investors to participate in markets outside of their own. 

I know it's heating up and I'd like to take advantage before I get priced out.

If she's not telling you why she stopped paying and she's not applying for assistance, then I suspect she's just taking advantage of the situation and stealing free rent.I would contact an attorney today to see what your options are and start the process.

I've been looking into maximizing performance and one scenario is the idea of building or acquiring a quadplex to take advantage of lower down payments / lower interest rates of a residential mortgage but then layering this with a max value rent by the room strategy.In many places it seems you can have 6-8 unrelated individuals in a home.Is anybody maximizing these joint strategies by building out a quadplex with 6-8 bedrooms per home and then renting out per room?
